THE AIRBAG DESTROYING
AT T E N T I O N !
It is forbidden the pyrotechnic system
handling near heating sources or open
fire because of risk of the syst em
undesirable releasing.
Dismount the airbag off the vehicle.
The operation of the airbag destroying is
to be performed outside the workshop. Conn ect the wiring necessary for
pyrotechnic gas generator tripping. Place the airbag pi llow on two wood
s pacers in order to avoid the con nector damaging with the ground.
Cover the assembly with 4 tires placed one
above the other.Unreel all wiring used for re leasing, for a
sufficient distance from airbag pillow 9about 10
meters). Connect the two connectors of the instrument
to a ba ttery.
After checking that no person is near airbag
pi l l ow, pro c e e d t o a i rba g de st ro yi ng by
simulta neously pushing the two buttons of the Ele
1287 device. REMARK:
In case the releasing is i mpossible (the
igniter of the pyrotechnic gas generator is
damaged), return the airbag pillow i n a new

APPLICATION CONDITIONS OF THE CHECKING DEFINED
AT DIAGNOSTIC
Each failure is interpreted for a specific memorizing type (present failure, memorized failure,
memorized or present failure).
The defined checking for each failure tracing is not to be applied unless the failure is interpreted
for the failure type declared by the CLIP tester.
If a failure is not interpreted in diagnostic or it is declared “present”, the diagnostic application
when the failure is only “memorized” will not allow the location of the memorizing origin of that
failure.
In this case, only a wiring and respective element connector checking must be performed (it
is recommended the wiring movement in order to try the passing visualization from state
“memorized failure” to state “present failure”).
If a failure is interpreted when it is declared “memorized”, the confirmation conditions of the
failure real presence (and the necessity of diagnostic application) are to be found at
”Recommendations” or at the beginning of the failure interpretation.
REMARK:
Before releasing diagnostic, the cont act must be off.
AT T E N T I O N !
Before any intervention at t he airbag system, i t i s obligatory t he UCE airbag blocking
by means of the CLIP tester, using the control “Computer blocking”. The confirmation
of this cont rol perform ing will be visual ized by permane nt lighting of the airbag
indicator from instrument panel and t he releasing line will be blocked, av oiding i n
this way the undesirable releasing of t he airbag during the intervention.
AT T E N T I O N !
⟨⟨⟨⟨If
the intervention is taking place after the vehicle has suffered a collision followed
by the driver’s airbag releasing, UCE airbag blocking is possible only after performing
its unblocking control performing.
⟨⟨ ⟨⟨Further to a shock causing the airbag releasing, the erasing of the memorized
failures it is possible only after dat a reading from “Imp act context”, followed by
“Computer unblocking” control.
⟨⟨ ⟨⟨The electrical measurements on the airbag releasing l ine are t o be pe rformed
only by using the function “ Airbag beam t ests” of the CL IP tester. It is strictly forbidden
the use in this purpose of the ohmmeter type measurement devices.
⟨⟨ ⟨⟨Before using the inert igniter, check that its resistance is between 1.8 – 2.5 ¿.
⟨⟨⟨⟨Ensure that during intervention, the computer supply voltage is not less than
10 V.

For a micro-disconnection failure, check the supplying lines of UCE airbag:
- check the wiring connector condition at the level of UCE airbag
- check the electric mass routing condition of UCE airbag.
- check the condition of the fuse designated for UCE airbag.
- check the condition and the correct tightening of the battery plugs.

Perform the necessary interventio ns in order to obtain a correct supply voltage of UCE airbag:
10.5 volts ± 0.1 < supply voltage< 15 volts ± 0.1

Set t he contact on, then block the computer by means of the CLIP t ester (see “Blocking UCE
airbag”)
Set the contact off and dismount the two attachment screws of the airbag on the steering wheel.
Check the correct connection of the airbag.
Disconnect the airbag then connect the inert igniter instead of it.
S et the contact on and perform a checking by means of the CLIP tester.
Replace the airbag if the state “present failure” is becoming “memorized failure”
Turn the contact off ; conect then reconect the connector of the rotating contact of under steering
wheel control.
Only CLIP tester is to be used for measuring the resistance in point C2 of the airbag circuit.
If the resulted value is not correct, replace t he control under steering wheel.
Reconnect the rotating contact of the control under steering wheel, disconnect the computer
connector and connect in its place the 30 pins adapter B40.
Only CLIP tester is to be used for measuring the resistance of the driver’s airbag releasing line,
using cable A of the 30 pins adapter.
If the resulted value is not correct, check the correct connection of the 30 pins adapter (pins 10
and 11) and replace the front wiring if necessary.
If after performing these checking no failure has been noticed, check the presence of the 5 pegs
for shunt unblocking, at the 30 pins connector of UCE airbag. Check the condition of the 30
ways connector of the airbag wiring (the connector blocking system…).
